Fix Google test Failure

Let's not use Google to test redirects since it changes depending on your
geographic location.  I changed the test to use httpbin.org, since
a lot of our tests already depend on httpbin.org anyway.

Somedays, I'd like to implement my own local mock HTTP server I
can do asserts against.  The test suite would just start it up,
and the server would record the requests, which I could then
retrieve and compare.

Closes #21
